+
+    ## Operations
+
+    ### config
+    Get the complete system configuration including all flows, prompts, token costs, etc.
+
+    ### list
+    List all configuration items of a specific type (e.g., all flows, all prompts).
+
+    ### get
+    Retrieve specific configuration items by type and key.
+
+    ### put
+    Create or update configuration values.
+
+    ### delete
+    Delete configuration items.
+
+    ## Configuration Types
+
+    - `flow` - Flow instance definitions
+    - `flow-blueprint` - Flow blueprint definitions (stored separately from flow instances)
+    - `prompt` - Prompt templates
+    - `token-cost` - Model token pricing
+    - `parameter-type` - Parameter type definitions
+    - `interface-description` - Interface descriptions
+    - Custom types as needed
+
+    ## Important Distinction
+
+    The **config service** manages *stored configuration*.
+    The **flow service** (`/api/v1/flow`) manages *running flow instances*.

+
+    - Use flow service to start/stop/manage running flows
+    - Use config service to store/retrieve flow definitions
+
+    ## Flow Instance Operations
+
+    ### start-flow
+    Start a new flow instance from a blueprint. The blueprint must exist (either built-in or created via put-blueprint).
+
+    Parameters are resolved from:
+    1. User-provided values (--param)
+    2. Default values from parameter type definitions
+    3. Controlled-by relationships
+
+    ### stop-flow
+    Stop a running flow instance. This terminates all processors and releases resources.
+
+    ### list-flows
+    List all currently running flow instances.
+
+    ### get-flow
+    Get details of a running flow including its configuration, parameters, and interface queue names.
+
+    ## Blueprint Operations
+
+    ### list-blueprints
+    List all available flow blueprints (built-in and custom).
+
+    ### get-blueprint
+    Retrieve a blueprint definition showing its structure, parameters, processors, and interfaces.
+
+    ### put-blueprint
+    Create or update a flow blueprint definition.
+
+    Blueprints define:
+    - **Class processors**: Shared across all instances of this blueprint
+    - **Flow processors**: Unique to each flow instance
+    - **Interfaces**: Entry points for external systems
+    - **Parameters**: Configurable values for customization
+
+    ### delete-blueprint
+    Delete a custom blueprint definition. Built-in blueprints cannot be deleted.
